Zulip’s unique threading saves me well
over an hour a day in working with our
distributed team of engineers and PMs
across 7+ time zones. We tried Slack,
Mattermost, and other team chat
products that claim to support
threading, and nothing handles
synchronous and asynchronous
communication so intuitively.

Akamai’s Zulip Enterprise deployment
connects over 2000 users around the planet.
The threading model of conversations
provides a large number of participants the
ability to engage in real, ongoing, and
substantive discussions, without the
overwhelming experience of many other chat
systems. This coordination across far-flung
teams has had a significant, positive impact
on the happiness and productivity of our
personnel, regardless of location or
seniority.

Andy Ellis, Chief Security Officer, Akamai

Choosing Zulip over Slack as our group chat is one
of the best decisions we've ever made. Zulip makes
it easy for our community of 1000 Recursers around
the world to stay involved, even years after their
batches finish. No other tool has a user
experience that scales to a community of our
size.
